PHP Get Image size when image is stored as byte array

I h开发者_开发问答ave image as binary string. (submitted via POST from C# app as byte array)

I can read it using imagecreatefromstring function. How can I get image size (width and height)?

getimagesize function takes filename as parametar. Is there alternative that can read image from binary string and return image size?

You can use imagesx and imagesy on gd resources.

Try imagesx(); and imagesy();
